''Unsupported or bad installed GPU driver?"

This is my first time using hashcat - or any cracking software for that matter. And unfortunately I'm getting an error while trying to bruteforce...
Which is, "Unsupported or bad installed GPU driver version detected!"

It says catalyst v13.1 is needed, which I have so I'm rather confused right now. I am using oclHashcat-plus v0.13.
The command I'm using is oclHashcat-plus64.exe -m 2500 -a 3 capture.hccap ?u?u?u?u?u?u?u?u

IIRC OpenCL support was dropped for the 4800 series and below by AMD.
Alright thanks for the heads up.
